METAL SCREEN.

Specification of Letters Patent 5,1906. Serial No. 291,825.

Patented Nov. 20, 1906.

Application filed December 1 following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

The invention relates to metallic-screen construction for windows and like openings, and is an improvement on the construction as shown in our former Letters Patent, N o. 802,090, and in our application for Letters Patent filed July 27, 1905, and bearing Serial No. 271,416.

Our irlvention consists in the construction and combination of the parts which we hereinafter describe, and specifically point out in the claims.

In the drawings, Figure 1 is a sectional view at line X X in Fig. 4. Fig. 2 is a perspective view of an end of one of the tubularfranie sides, and Fig. 3 is a perspective view of the end of an adjoining tubular-frame side which fits into the end shown in Fi 2 to form a corner. Fig. 4 is a full-size I lan view of the screen and guides on the wim owcasing with the central portions broken away vertically and horizontally. Fig. 5 is a sectional view smnlar to that shown in Fig. 1 of a modification of the screen. Flg. 6 1s a pcrspective view of our improved guide-strip for the screen on the window-casing. Fig. 7 isa side elevation of a portion of the screen and frame, showing an adjustable shoe bearing on the guide-strip; and Fig. 8 is an elevation of the opposite side of said shoe, the tube being shown in section. Fig. 9 is a perspective view of the tubular corner-piece inserted within the corner of the screen-frame, and Fig. 10 shows a similar view of said corner- )iece'. Fig. 11 is an elevation of an adjustable lift and shows the lift attached to a section of the frame side; and Fig. 12 is a sectional view of the frame side, showing an end elevation of the lift and the strip for ad justably attaching said lift in the. wire-retaining groove. Fi 13 is a perspective view of the retaining-tn e for the screerrwire, showing the slot therein for the adjusting-screw of the spring-shoe.

I Similar numerals refer to the corresponding arts in the several views.

e numeral 10 indicates the tubular sheet- Inetal frame, which consists of the horizontal top and bottom pieces 11. and the vertical lateral pieces 12 and 13. These tubular-frame sides are each formed from single strips of sheet metal by means of suitable dies and presses. The lengthwise edges 14 of the strip are united and bent in a channel or solder or brazing, throughout their contactmg surfaces from the point of firstcontact at 15 to the outer edge 16 of the flange which forms one side of the channel 17. This forms the frame side in a solid tube having a closed opening 18.

Each of the corners is formed in a miterjoint, as follows: One of the ends 19 is cut on the mitral line, exce ting the outer channel Each tubular corner is stiffened and madestrong by means of tubular corner-pieces 29, which are nserted within the tubular corner,

Fig. 4. Corner-pieces 29 are made a solid tube and fit tightly within the tubular opening 18 at each corner of the frame, the size of the difl'erent sides of the tubular-corner-piece 29 being made to fit the opening in the frame side. Corner-piece 29 may be soldered or fastened within the tubular-frame corner, though it forms a strong stiffening-brace without such fastening.

The lateral frame sides 12 and 13 are formed with lengthwise channels bent in the sheet metal to receive the guidestrips 23 on the window-casing. Channel or groove 24 in frame side 13 is made of suffieient depth to receive the elliptical springs 25,which s rings are preferably made as shown in our ormer Letters Patent, No. 802,090, spaced slots'26 being provided in the bottom of channel 24 25. Channel 24 extends beyond the mitcred end 19 and forms a strong brace to stiff en the as shown in Fig. 9 and in dotted outline to be engaged by the angular ends of springs groove 17 and then attached, by means of part 24, which exten s to the opposite end, as

. to admit the guide-stri 23.

The groove is bent in the frame side and has its ends formed similar to roove 24. It is often desirable, however, to iave a greater range of adjustability than elliptical s rings 25-will allow. This is provided for in t e following manner: In the modifi cation shown in 5, instead of the shallow groove 30, a deeper ove 31 is formed witha low side 32 spring-shoe 33 is place inchannel 31. by means of spaced slots 26 in the bottom of the channel, the same as for spring 25. Springshoe 33 and elliptical s ring 25 have their outer bearing-surfaces ormed in a hollow groove to receive the round face of guidestrips 23. Spring-shoe 33 has a projection 34, which extends throu h a slot 35 in the bottom of groove 31. rejection 34 keeps shoe 33 from tlilpping sidewise. Shoe 33 is also given stab' ity and a closer adjustment by means of screw 36, which extends through frame side 12 and against the inner side of shoey33. It is apparent that an desired amount of leeway can be glven to s oe 33 by means-of screw 36. It is also obvious that with the deep groove 24 in frame-piece 13 it wouldbe impossible to admit to a corres ondingly deep groove in frame-piece 12 on the opposite side of the frame without the doing away with the side of the groove, as

The screenrwire' 37 is. attached to the tubular frame in groove 17 by means of the s ring-tube 38, as in our former construction, the mouth of channel 17 being slidably contracted by means of the inward projection of edge 16 and the lengthwise outward projection of edge 39. A crosswise cut 40, as

shown inFigs. 5 and 13, is made in tube 38 .to accommodate adjustingl-screw 36 for shoe 33.

Guide-strips 23 on t e window-easing are made of wood. The sheet-metal cap 41 extends onto the strip a sufficient distance to serve the p ose of contact with the shoe or 5 rin of t 0 frame side, but leaves the woo en base free for fitting to the windowcasing. Window-casings are often out of true, and our improved guide-strip allows of the wood beinqcut away to exactly adjust the space between the stri )8, so that the screen will run true. Thus t e strip may be much narrower at mic and than the other, as

shown in the strips at each side of Fig. 4, wherein the lower end, as shown in section, is much narrower than, the upper end. Sheet-metal cap 41 is clasped onto the headlike edge of the wood base, the edges pressing into the wood, as at 44.

An elliptical This clasp is sullicient to hold theeap 41 serves, also, another important m preventing the splitting of the strip. It is obvious that the ca 41, clasping the strip at each side at 44, will the wood b the driving of the nails 35. Cap 41 also orms a strong hold for the head of the nails. This strip 23 admits of close fitting to the window-sash, since the screenframe 10 can be placed against the sash, shown atthe dotted line 46 in 1. Our improved guide-strip is made the subject of a separate application, Serial No. 291,826, of even date with this application.

It is often desirable to attach a lift at differentportions of the screen-frame. By our improved construction we are enabled to so ad ustably place the lifts in the following manner: A suitable handle 42 for the lift is provided with a strip of sheet metal 43, pivtherefrom 'a suilicient distance to be e i .nnderneath the screen-wire 37 and in prevent the splitting of strip 38 in channel 17. The said lockin strip and screen-wire hold the lift firmly in place, and it is obvious that the lift can be placed at any point around the inner side of the screen-frame at which it is desired.

We claim as new 1. Ina window-screen, a frame having a channel along its inner edge for the screenwire, a retaining-strip for said wire in said channel, a lift consistin of a wire loo ha ing a metal strip pivota ly attached t ereto said strip to be held in said channel by said screen-wire and retaining-strip. l
